SHUTTER-OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 453,640, dated June 9,1891.

Application filed November 3, 1890. Serial No. 370,200- (No model.)

To all whom, it may concern:

Be it known that I, WALTER O. JARvIs, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements in Devicesfor Opening and Closing Sliding Shutters, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention relates to appliances for operating the fire-shutters ofwarehouses and other buildings; and the objects of my invention are,first, to provide means whereby one or more rows of shutters can in caseof fire be either opened or closed. from a point remote from the flames,and, secondly, to provide means for effectively and quickly connectingor disconnecting any one of the shutters of a story from the others.

To the above purposes my invention consists in certain peculiar andnovel features of construction and arrangement, as hereinafterdescribed, and pointed out in the appended claim.

In order that my invention may be fully understood, 1 will proceed. todescribe it with reference to the accompanying drawings, in which-Figure 1 is a front elevation of a building with my improvements appliedthereto. Fig. 2 is a transverse vertical section of the same on the lineman of Fig. 1. Fig. 3 is a section on line y 3/ of Fig. 1.

In the said drawings, A designates one wall of a warehouse or otherbuilding, and B the windows thereof, there being a number of windows foreach story and a number of stories to the building, either precisely asshown or more or less, as may be.

G designate a number of shutters, one of which is designed to close oropen each of the windows B. To the lower portion of the outer side ofeach of these shutters are attached a number of brackets E, each ofwhich is of an gular form, so as to offset at its lower portion from thesurface of the shutter, as shown at e, and each of which carries on theinner side of its lower end a grooved wheel or roller F. Along the outerside of the wall and about on the level of the sills of the windows Bare placed a number of rods or tracks g, the ends of which are bolted orotherwise suitably sethe rollers F above described.

cured to supports II, which project horizontally outward from the wallof the building, and each of which is a bar or short piece of inetaldriven into or otherwise suitably secured to the wall. The rollers orwheels F run upon the upper sides of the rods or tracks g, and thussupport the weight of the shutters. Upon the outer side of the upperportion of each shutter B is also secured a number of angular bracketsE, the lower parts 6 of which also offset from the shutter, and whichcarry at the inner side of their lower ends grooved wheels or rollers F,similar to These upper rollers F run upon rods or tracks 9, similar tothe rods or tracks above described and similarly supported at their endsby supports H; but the uppertracks extend along the upper parts of thewindows, and the wheels or rollers F, which run upon them, serve inaddition to sustaining a portion of the weight of the shutters, theadditional purpose of retainin g the shutters in proper verticalposition.

Upon the upper part of the outer side of each of the shutters C issecured by bolts or in other suitable manner a plate D, which isprovided on its upper side with two oppositely-disposed hooks (Z. Theseveral shutters of each story are connected together by short cables'27, the ends of which are connected to the two adjacent hooks (Z of thesucceeding shutters. To the outer hooks of the two end shutters of eachstory are connected the up per ends of two cables I, each of whichextends laterally away from the row of shutters and is led over a pulleyJ. Each of these pulleys J is mounted in the lower part of a bracket orhanger K, bolted or otherwise secured to the outer side of the building.From the pulleys J the cables I extend downward in two sets at each endof the wall, and the lower end of each of said cables is passed beneatha pulley L and is finally wound upon a shaft 0, located adjacent to thesaid pulley L. It will be observed that there are a number of pulleys Land shafts O at each end of the wall, and that each pulley L has acompanion shaft 0, while the shafts and pulleys are located near theground. Each pulley L is mounted in a hanger M, and each shaft 0 extendsthrough the wall and is provided at each end with an angular portionadapted to receive a crank-handle P. The inner ends of the shafts aredesigned to be in the Watchmans apartment. It will thus be seen that inthe event of a fire in the building all of the shutters in any one orall of the stories can be quickly closed from the ground or from a lowerapartment of the building, and that as the fire progresses and it isdesired to direct streams of water into one or more of the stories theshutters of each story can be opened and closed again at points soentirely remote from the fire as to avoid any exposure of the operatorto danger. It will be further seen that the short cables ibetween eachtwo inner shutters of each story not only facilitate the firstapplication of the mechanism to buildings, but greatly simplify theconstruction and enable repairs to be made without deranging the entireWorking mechanism of a story.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

An improved shutter-working mechanism for fire-shutters, comprising aseries of sliding shutters for the windows of each story of thebuilding, upper and lower rods or tracks extending across the windows,and upper and lower rollers secured to the shutters and running uponsaid tracks, plates D, secured to the shutters, oppositely -disposedhooks d thereon, short cables connecting the hooks of the successiveshutters, longer cables attached to the outer hooks of the outershutters, winding-shafts 0, j ournaled in the wall of the building andhaving both their outer and inner ends angular, whereby they may beoperated from the outside or inside of the building, the said shaftsreceiving the lower ends of the longer cables, and pulleys secured onthe wall, around which the cables pass, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
